Pandora Media may team up with a private equity firm in exchange for cash to help expand the business, The Post has learned.

The streaming radio stalwart has been in talks with Providence Equity Partners, Silver Lake and KKR, among others, sources said. Chief Executive Tim Westergren just launched a paid on-demand service and has ambitions to roll it out beyond North America — but needs cash to pay hefty royalties to music labels.

The conversations might indicate that Pandora has given up on a sale, but sources say that door is still open and talks about a strategic investment are happening in tandem.
